Tried to increase Q_TAILSIT_ANGLE TO 4500 and then it shaked heaveli when flying forwards.
Reduced Q_TAILSIT_THSCMX to 1.0, as also letpi recomended, and now it is calm.
Will soon increase Q_TALSIT_ANGLE TO 5500.
Thanks for this great param.
I set Q_SPIN_MIN from 0.15 to 0.3, and Q_M_THST_HOVER from 0.6 to 0.65 and great success!
The Backtransition to QHover ist (nearly) perfect. It overshoots the vertical position with 10° only, the altitude by 7 to 9 m and then sinks (still vertical) 2m.
And this with a Transtition-approach Speed of 56 kmh.
Thank to both for your help, now I’m happy.
I have another question.
During FBWB I can see, the Throttle_out changes (slow oscillation) from 30to70% with constant RC_IN_C3 of 1450.
I can’t see any corelation to a value like altitude, GPS Speed or Roll- or Pitch-Angle.
The ARSPD_USE ist still 0
Can you explain what happens?
Sorry, no video, due to the strong wind absorbed, forgot to swich ON.
